which the following is aspeciication.

My invention relates "particularly to a transmission-'gearing for automobile're engines, andthe objecty of theinvention is to provide a mechanism by means of which the power of the engine can be easily' and quickly shifted from the c'lifferential' and the road driving-` mechanism to the pumpwhen stationed at a hydrant, orfotherwater supply, and be as readily. transferred 4to the differential, and the road it is desired to vstop the pump and change the position ofthe engine or return it to the lire-house;

A furtherA object is to provide ashifting mechanism controlled by the forward and backward movement of a single lever, operating in one direction to shift the drive from differential to the pump and in the other direction to shift the` power from the pump back tothe differential'. i i

' Other objects of the invention will appear from v the following detailed description.

The invention consists generally in varihereinafter described and particularly pointedout in theclaims. Y v

Referring to Fig. 3, 27 represents a cas ing, depending below the nshifter box.A A stud v28 has a-universal bearing, lpreferably ball and socketfat 29'in the bottomlof said bofX. The upper end of;said stud has la universal bearing .at 30 in the bottom of the slide f6. rlhe .lower wall Aof said shifter box has lanfirregular slot V31 therein in which the upper end of the stud 28 is movable lengthwise of the box and ytransversely thereof to effect lthe desired movement of the slide and connect its couplings with the transmission pinion. The lower end of 'the stud 28 has a crank 32 thereon that is connected by :suitable means, such as a rod 33, with the single operating lever 34 that is mounted `at the forward portion of the engine adjacent to vthe drivers seat, (not shown), and ,provided with the usual quaddrant 35 4having the intermediate neutral position and one =end for :the running connection and the other for .the pump connection, it being only necessary for the driver to grasp tliis'lever and throw it back and forth on the quadrant to shift .the couplings and .change tliedrive fromr the differential to the pump and vice versa. p t

I prefer to mount a. stud 28 in such a manner that the Virregular movement of the `shifter lslide 4can be accomplished through or backward ,movement of the drivers lever in a straight line. I therefore (provide an arm 36 ,projecting from the stud substantially at right angles thereto and having a `ball kv37 at-its extremity, loosely mounted in a lguideBS that is secured to the wall .of the casing 27 .andforming a fulcrum on which the stud 28 mayy rock during 'a portion o f its movement. This Vstud Iis also provided l.with oppositely arranged corresponding arms I39 and v4.0, bothfhaving vballs A41 at their outer ends fitting within guides .42 and 43, also secured `to the wall A All of these-guides are `held inA place by suitable means,4 such as set a single forward "seews si. lamented in the Well @fthe easing tion indicated in Fig.
